Abstract

SISTEMA DE MOTORES HIDRÁULICOS EM GUINDASTES DE MANUSEIO DE CONTÊINERES. A invenção se refere a motores hidráulicos para atuar e controlar um sistema anti-oscilação em guindastes de manuseio de contêineres. Guindastes de manuseio de contêineres apresentam o seguinte problema, a saber, quando o carro se move os cabos que suportam o travessão de carga oscilam longitudinalmente em relação ao movimento mencionado anteriormente. Os sistemas atualmente usados para reduzir o referido movimento de oscilação são inconvenientes porque (i) compreendem numerosos elementos de transmissao de potencia, dessa forma gerando problemas de manutenção e (ii) as duas principais funções dos mesmos são executadas separadamente, isto é, transmissão de movimento e redução de oscilação. Os problemas mencionados anteriormente podem ser resolvidos com um sistema de acionamento independente autônomo usando motores hidráulicos, dessa forma, tornando o conjunto de acionamento de transmissão de potência simples, robusto, confiável e fácil de manter. Além disso, os motores executam as funções principais simultaneamente, isto é, produzindo o movimento e reduzindo as oscilações. De acordo com a invenção, dispositivos limitadores de pressão são usados para amortecer os pontos de pressão aplicados ao motor durante o movimento de oscilação. O sistema equilibra a pressão sobre os motores e, desta maneira, desvia o movimento de oscilação.HYDRAULIC MOTOR SYSTEM IN CONTAINER HANDLING CRANES. The invention relates to hydraulic motors for actuating and controlling an anti-roll system in container handling cranes. Container handling cranes present the following problem, namely when the carriage moves the cables supporting the load crossbar swing longitudinally with respect to the movement mentioned above. The systems currently used to reduce said oscillating motion are inconvenient because (i) comprise numerous power transmission elements, thereby generating maintenance problems and (ii) the two main functions thereof are performed separately, i.e. movement and oscillation reduction. The aforementioned problems can be solved with a standalone independent drive system using hydraulic motors, thereby making the power transmission drive assembly simple, robust, reliable and easy to maintain. In addition, motors perform the main functions simultaneously, ie producing motion and reducing oscillations. According to the invention, pressure limiting devices are used to dampen the pressure points applied to the motor during oscillating motion. The system balances the pressure on the motors and thus deflects the oscillating motion.
